My hands start aching and then numb fingers while riding for only a short period ... especially on the throttle side Old age , old injuries and riding a total sports bike probably doesnt help , but thats life in the fast lane and nothing else gives me a problem I bought these to see if they help, to wear under my leather gloves .... time will tell https://www.chemistwarehouse.com.au/buy/71581/bodyassist-cotton-arthritis-gloves-large-1-pair A test ride might have to wait though as I have ongoing construction happening in the staging lane
I have similar problems and use the foam over grips on my bikes as well as a throttle lock to be able on long straights to lock the throttle on and rest my hands/shoulder. https://www.google.com/search?q=gri...7j0l6j69i60.4864j0j7&sourceid=chrome&ie=UTF-8 https://www.google.com/search?q=vis...3.69i57j0l7.5247j0j7&sourceid=chrome&ie=UTF-8
This is the NEP throttle lock that I have on three of my bikes. https://www.amazon.com/Sound-Off-Recreational-Control-MCCC20-P/dp/B000WJGLY8 https://www.ebay.com.au/itm/NEP-CC-...IOnTopCombiner&_trksid=p2047675.c100752.m1982 Have seen them cheaper here in OZ.
